What is the concentration of your solution?

Chemistry
1 answer:
Nataliya [291]3 years ago
3 0

Answer:

The volume of unknown sample would be 2.5 mL.

Explanation:

Given data:

Molarity of unknown sample=M₁= 1 M

Molarity of sulfuric acid = M₂= 0.100 M

Volume of sulfuric acid = V₂= 25 mL

Volume of unknown sample=V₁  = ?

Solution:

Formula:

M₁V₁   =  M₂V₂

Now we will put the values in formula:

1M × V₁   =  0.100 M × 25 mL

V₁   =  0.100 M × 25 mL / 1 M

V₁   = 2.5 mL

The volume of unknown sample would be 2.5 mL.

What is the mass in grams of 8.65 mol C8H18?
aliina [53]

Answer:

m = 998 g

Explanation:

Hello there!

In this case, according to the definition of the molar mass as the mass of one mole of the compound, it is possible to state the 1 mole of C8H18 has a mass of 114.26 grams; therefore, the mass in 8.65 moles turn out to be:

m=8.65mol*\frac{114.26g}{1mol}\\\\m=998g

In agreement to the notation requirement.

Best regards!

We say that salts will dissociate but acids will react with water. We say that acids will
Paha777 [63]

Answer:

ionize

Explanation:

Acids are chemical substances that lose/donate their hydrogen ion (H+) when they react with water. This property of acids is termed IONIZATION. In a chemical reaction involving acids and bases, acids release their proton or hydrogen ion (H+) in the presence of water solutions to form a conjugate base, which is usually an anion.

For example, in the chemical reaction;

HX + H20 -------> X- + H30+

HX is the acid because it loses its electron to water and forms the anion, X-, which is the conjugate base. Hence, it can be said that acid HX ionizes in water.

_______ properties depend on the concentration of a solute in a solution but not on the identity of the solute.
Grace [21]

This problem is providing us with a statement in which we need to figure out the word fitting in the blank. At the end, after analyzing the information, the word turns out to be colligative as show below:

<h3>Colligative properties.</h3>

In chemistry, colligative properties of solutions account for the behavior of a solution with respect to the pure solvent, to which a solute is added.

Among them, we have boiling point elevation, freezing point depression, vapor pressure lowering and osmotic pressure, which are all affected by the concentration of the solute but not by the identity of the solute.

In such a way, we conclude that the correct word that fits in the blank is colligative as shown below:

"Colligative properties depend on the concentration of a solute in a solution but not on the identity of the solute."
